Started trading about two years ago. Made all the rookie mistakes, and lost $10K+. I didn't declare in taxes, assuming that a negative income is of no interest to CRA. However, the turnaround seems to be happening, and I hope to make small profit by years' end, and hopefully more next year. My question is: can I carry last year's loss to this year's (or next year's) profits, and write off the loss against anything I make (until my profits exceed my loss of last year)? Any insight appreciated, thanks in advance.
